Power Transmission

In power transmission, we construct, rebuild, upgrade, and reconductor high voltage transmission lines and substations. Historically, Barnard has worked with more than 25 utility clients, many under repeat contracts. In recent years, that work has come to include power transmission and substation projects. We have built a team that combines some of our long-term professionals well practiced in our management style, our aggressive scheduling, and our focus on safety and quality with highly experienced, well respected technicians who’ve joined Barnard for a growth opportunity. At Barnard, we know how to build relationships with landowners as well as owners, so that when the work is complete, every stakeholder views the project as a success.
